Microsoft enforces MFA requirements for user login to Azure portal for all tenants

Password spray attacks on accounts have increased rapidly in recent months. As a result, the security risks for accounts that do not use MFA for authentication have increased significantly. Microsoft works in the past on different ways to enable MFA for all users they work with Azure and Microsoft 365. One first try was the activation of security defaults, but this can be deactivated by user.

Based on this development and for other reason Microsoft announced the enforcement for Mutlifactor authentication for all sign-in/access to the Azure Portal. This announcement was a little suprise and bringe some challenges to organization espesically when we take a look at service principals and break glass accounts. Don´t get me wrong, it is mandatory to enable MFA for all users they access your tenant and have a valid and regulary reviewed Conditional Access policy in place. But for some special accounts this was not the focus or recommended. In this article I will explain how Microsoft rollouts this enforcement which steps you have to proof and how you can ensure that you are not affected or prepared for the upcoming changes.

Awarded as Microsoft MVP for Azure and Microsoft Security 2024-2025

I am pleased to announce that I have once again been recognized as a Microsoft MVP for Azure and Security in 2024-2025. This year there were some internal changes and the announcement was therefore postponed to July 10. So late Wednesday the mail came and I saw, just before my birthday, that I was again awarded in the following categories:

  • MVP for Microsoft Azure Compute Infrastructure
  • MVP for Cloud Security

What a great surprise

It is still an honor to be part of this family. There are many people who have supported me along the way, without whom this award would not have been possible. A big thank you goes to my wife Jessica, without her support this would not have been possible. There are many people who have become true friends during this time and to whom I am very grateful for their support, like Eric Berg, Thomas Naunheim, Marcel Meurer and Tom Janetscheck and many others. Also a big thank you to my Azure Bonn Orga Team, René de la Motte and Thomas Naunheim without whom the many Meetups and the Cloud Identity Summit would only be half as nice.

But this award is not possible without the community and the recognition from Microsoft, so a big thank you for that.

If you’re interested in what conferences you can find me at in 2024, feel free to check out my upcoming community events page.

Guest on Geeksprech Podcast about FinOps and/or Azure Cost Management (Governance)

In 2023 I was at some conferences where I held a session about Azure Cost Management and I´ve discussed this topic also a couple of times with my best buddy Eric Berg.

He invited me to his podcast Geeksprech where we talked and discuss what FinOps is and why in some cases it`s the same as cloud governance and cost management without the melodious and modern name 🙂

The new Azure Update Manager is GA – Part 2 – How it works and the valuable new features

In the first part of this article (Three-big-reasons-to-migrate-to-update-manager-and-forget-the-classic-update-management-center) I dived into the improvements and reasons why Micrsoft introduce Azure Update Manager as a successor of the classic Update Management Center solution based on Azure Automation. In this part, I will explain how it works and what major improvements and new functions the Azure Update Manager offers

Please note: Azure Update Center is based on Azure Automation and needs the Microsoft Monitoring Agent. The MMA has been discontinued and will no longer be supported after August 2024. Support for Update Center has therefore also been discontinued.

2nd note: Microsoft will charged at a daily prorated value of 0.16/server/day which equates to approximately $5 USD/server/month beginning 1 February 2024 for customers using Azure Update Manager on Arc-enabled servers.

Enable granular pricing for Defender for Servers P1 or P2 on specific resources within your subscription via API/Powershell

Microsoft model for a scalable Cloud Adtoption is based on the Enterprise Scale Architecture and I think this is a scalable and useful modell for every customer that uses Azure ressources. It´s based on the definition to granulary devide the workloads in different subscriptions and gives via Management Groups the possibility to group this differnent subscription into workload groups like Development, Core, etc. I know many customers struggle with this model and mistakenly think that Enterprise Scale is a reference to Enterprise customers, but this is not the case.

Based on the Enterprise Scale Architecture some services and security features can only be activated on subscription level to guarante that each resource inside the subscription is secured. This basis makes it even more important for customers to consider the Enterprise Scale Architecture or to orient themselves towards it.

The Microsoft Defender for Cloud and especially the Defender for Server P1 and P2 plans can only be activated on subscription level in the past. Microsoft has decided to change this and now allow plans to be activated at resource level (per server). It is important to understand that the principled approach activating on Subscription Level and the Enterprise Scale architecture are still valid and needed and this possibility is only a concession to cover certain requirements:

  • manage security configurations at a lower hierarchy level
  • flexibility for excluding specific resources (VMs) inside the subscription
  • enable different plans on subscription because for implementation of Enterprise Scale approach

How to deactivate Hyper-threading on Azure VMs in an easy way without Microsoft support

In my current project we have the requirement to deactivate Hyper-threading on some Azure VMs. There are some Azure VMs available without Hyper-threading which can be found on the Azure compute unit site where Microsoft published a table with VM SKUs sizes where the “vCPU: Core” give a hint about VMs which are not having HT integrated. But this sizes are very limited and we have some requirements from licensing side to disable Hyper-threading and there also some applications which have a better performance when HT is disabled.

The new Azure Update Manager is GA Part 1 – three big reasons to migrate to Update Center and forget the classic Update Management Center

Microsoft released a completely new designed Update solution for Azure which supports VMs running in Hybrid- and Cloud-only environments with the name Azure Update Manager (formerly known as Update Management Center). This new solution is completely new and not based on the Azure Automation solution. The Azure Automation solution is based on the Microsoft Monitoring Agent (MMA – Log Analytics Agent) which will be retired on 31 august 2024.

The new solution cut off a lot of dependencies and fully compatible with Azure Arc. The reason that the solution, which has been in preview for a long time, is now announced as GA is that this solution supports the extended security updates for Windows Server 2012, which recently went out of extended support.

Please note: Azure Update Center is based on Azure Automation and needs the Microsoft Monitoring Agent. The MMA has been discontinued and will no longer be supported after August 2024. Support for Update Center has therefore also been discontinued.

The new Azure Update Manager in preview named as Update Management Center, was needed, because of an consistent Update Management over all VMs including VMs, that are integrated via Azure Arc.

The new solution offers significante improvements:

  • Zero on-boarding with Azure Policy support
  • No dependencies on Log Analytics or Azure Automation
  • Built as native functionallity on Azure Compute and Azure Arc for Servers
  • Support Azure RBAC and roles based of ARM in Azure
  • No manual intervention is needed as long as Azure-VM- or Arc-agent is running
  • Gathered information available for analysis via Azure Resource Graph
  • Support for automatic VM guest patching and hotpatching
  • Manage Extended Security Updates (ESU) for out of supoort WS2012

In this article I will give you a overview about the solution and how you can configure this solution for your VMs. Since I’ve been using it in a large Azure environment since the Public Preview release, I’ll point out some recommendations and pitfalls.
